Any time we see photos of one of the Olsen twins, we always have to slow down to double-check if it’s Ashley or Mary-Kate. But when they both went out this weekend in gray T-shirts and skinny jeans, we could barely figure it out! (For the record, it’s Mary-Kate on the left, and Ashley on the right). Mary-Kate accessorized her slouchy shirt with a big belt, Christian Louboutin pumps and white Ray Ban sunglasses. Ashley pairs her slimmer American Apparel t-shirt and Earnest Sewn Harlan 18 jeans with Mosley Tribe aviators, a Givenchy “Nightingale” bag and major wedge heels. We want to know which twin’s style you like better! Tell us: Who wears their gray t-shirt and jeans better? Mary-Kate or Ashley?
